commit ce5e2928 upstream.

Fix reset-resume handling which failed to resubmit the read and
interrupt URBs, thereby leaving a port that was open before suspend in a
broken state until closed and reopened.

Fixes: 1ded7ea4 ("USB: ch341 serial: fix port number changed after resume")
Fixes: 2bfd1c96 ("USB: serial: ch341: remove reset_resume callback")
